Description

  The present invention relates to a product recycling system that manages the sale and purchase of recycled products, and more particularly to a product recycling system that checks illegally obtained products at the time of purchase.

  In recent years, from the standpoint of reducing environmental burdens, consumer needs have changed as consumer needs have increased, and used products have been reviewed. Against this background, a recycling business that purchases unnecessary items and sells them again as second-hand products is becoming popular. There are various items that can be recycled, such as books, CDs, game software, home appliances, clothes, jewelry, and precious metals. Among them, books are especially sold, and once they are read, they become unnecessary. Because it tends to be, the amount handled as recycled products is large.

  On the other hand, illegally obtaining a book by shoplifting or the like, and obtaining the money by selling the obtained book to a recycling company is a social problem. Therefore, when purchasing a book, the recycler should not purchase multiple copies of the same book, or if the purchase price exceeds a certain amount, verify the identity of the person with identification, etc., and record the purchase record with the person's signature. Or take it.

  On the other hand, RFID (Radio Frequency Identification) tags have been used as means for preventing goods from being taken out illegally due to shoplifting. Here, the RFID tag will be described. FIG. 12 is a block diagram showing an RFID tag, and FIG. 13 is a block diagram showing a reader / writer. In FIG. 12, the RFID tag 1 includes a base material 2, an IC chip 3, and an antenna 4 connected to the IC chip 3. In FIG. 13, the reader / writer 5 includes a controller 6 and an antenna 7 connected to the controller 6. FIG. 14 is a block diagram showing the inside of the IC chip. In FIG. 14, the IC chip 3 includes a transmission unit 8 and a reception unit 9 for communicating with the reader / writer 5, a memory unit 10 for storing data, and a power supply unit 11.

  When the RFID tag 1 configured as described above is brought close to the antenna 7 of the reader / writer 5, an electromotive force is generated when the antenna 4 of the RFID tag 1 receives a radio wave from the antenna 7, and the power source unit 11 Operating power is generated based on the power. As a result, the IC chip 3 operates to exchange data with the reader / writer 5.

  Next, a mechanism for preventing unauthorized take-out of merchandise using an RFID tag will be described. First, an RFID tag is attached to a product cover or the like, and a gate is provided near the store entrance. The gate has an RFID reader function, and a warning sound is emitted when a product with an RFID tag passes through the gate. When a product is properly purchased, the cover with the RFID tag is removed and the product is delivered to the purchaser. If the product is taken out with the RFID tag attached due to shoplifting, etc., a warning will be given when the gate passes. A sound is generated, which can prevent unauthorized take-out.

  There is a non-contact IC card using a non-contact communication technology similar to an RFID tag. Similarly to the RFID tag, the non-contact IC card includes a base material, an IC chip, and an antenna. When the contactless IC card is brought close to the reader / writer, the IC chip operates by receiving radio waves from the reader / writer antenna, and can transmit and receive data. it can. Some non-contact IC cards have a payment function similar to cash by recording “money” information in the memory portion of the IC chip, and recently, some are built into mobile phones.

  Generally, RFID tags and non-contact IC cards are attached to “things”, and those that identify “things” are called RFID tags. What is supposed to be handled by a person by doing so is called a non-contact IC card.

  In the system of selling and purchasing books as recycled products, the RFID tag is attached to products such as books to prevent unauthorized take-out, but if the RFID tag is removed before passing through the gate, the product Is taken out of the store. Even if an illegally taken-out product is brought into the Shinko bookstore for sale, there is no way to judge whether the product was obtained illegally. Could not prevent.

As means for preventing this, for example, there is one disclosed in Japanese Patent Application Laid-Open No. 2004-234403. This is because ID information is attached to a product, ID information of the product is registered in the product information database of the information processing apparatus when the product is sold, and the product information database stores the product information when purchasing the product The product information is checked to determine whether or not to purchase.
JP 2004-234403 A

  However, in the system disclosed in the above literature, when the product is purchased, if the ID information of the product that has been purchased is registered with the information management center together with the sales information, it can be sold as a used product. There is a problem that even if a purchased product is stolen and illegally obtained by a third party, the stolen product can be sold.

  Therefore, the present invention provides a product recycling system that can prevent the purchase of a product that has been purchased by a third party illegally, even if the product is properly purchased.

  In order to solve the above problems, the present invention provides a storage unit that is provided in a recycled product and stores transaction history information of the recycled product, a first reading device that reads the transaction history information of the storage unit, and the reading device.

  In this embodiment, a user who wants to receive this service needs to register as a member in advance. The member registration method will be described with reference to FIG. FIG. 2 is a flowchart showing a member registration method. First, the user 24 accesses the homepage of the recycling service provider 22 from the mobile phone 25 owned by the user 24 via the network 36 (step 1), and downloads a member registration program (step 2).

  Next, the user 24 activates the member registration program installed in the mobile phone 25 (step 3), inputs information necessary for registration, and presses the completion button. The input information is transmitted to the computer 28 of the recycling service provider 22 through the network 36 when the completion button is pressed (step 4). The information required for membership registration includes the address, name, age, identification card type and number of the user 24. For example, when the registration program is started, an input screen as shown in FIG. You can enter various information. FIG. 3 is an explanatory diagram showing a registration information input screen. In FIG. 3, the display screen is above the dotted line at the center, and the display below the dotted line is not actually displayed, but is displayed by scrolling.

  The computer 28 of the recycling service provider 22 checks the transmitted data for membership registration (step 5), displays an error if the input information is incomplete (step 6), returns to the input screen again, and enters the input information. Prompt to correct. If the input information is not incomplete, an ID number is assigned next (step 7), and the member registration information and ID number are stored in the member information database 29 (step 8).

  Next, the computer 28 of the recycling service provider 22 transmits the ID number to the mobile phone 25 of the user 24 (step 9), and the member registration program incorporates the transmitted ID number into the mobile phone 25 of the user 24. The data is stored in the memory in the non-contact IC card 31 (step 10). The user 24 confirms from the message on the screen of the mobile phone 25 that the ID number has been normally stored in the memory, and then ends the member registration program (step 11). This completes the membership registration procedure.

  Next, a method for the user 24 to purchase a book at the bookstore 26 will be described with reference to FIG. FIG. 4 is a flowchart showing processing at the time of purchasing a book. As shown in FIG. 5, the RFID tag 35 is attached to the book 34 in advance, and information about the book is recorded in the memory in the RFID tag 35. FIG. 5 is an explanatory view showing an RFID tag attached to a book. As shown in FIG. 6, the information to be recorded includes an ISBN (International Standard Book Number) code 38a for identifying a book, a sales object and an issue form, a classification code 38b indicating the contents of the book, and a book having the same contents. It consists of a serial number 38c for identification and a regular price code 38d indicating the regular price of the book. FIG. 6 is an explanatory diagram showing recording information of the RFID tag.

  When the user 24 brings the book 34 to be purchased to the cash register (step 21), the cashier of the book store 26 reads the RFID tag 35 built in the book 34 with the RFID tag reader / writer 33 connected to the POS terminal 27. (Step 22). Data read by the RFID tag reader / writer 33 is transmitted from the POS terminal 27 to the computer 28 of the service provider 22 via the network 36 (step 23).

  The computer 28 collates the data of the transmitted book 34 with the book information stored in the book information database 30 (step 24). In the book information database 30, ISBN codes, classification codes, serial numbers, and regular price codes of all books handled by the bookstore 26 are registered. Here, a book 34 to be purchased by the user 24 is registered. It is checked whether or not. The computer 28 transmits the verification result to the POS terminal 27 (step 24).

  The cashier determines the transmitted verification result from the display screen of the POS terminal 27 (step 25), and if the book 34 to be purchased is registered (OK), the cashier carries it to the user 24. Presentation of the telephone 25 is requested (step 26). When the user 24 brings the mobile phone 25 close to the non-contact IC card reader / writer 33 connected to the POS terminal 27, the non-contact IC card reader / writer 32 records in the memory of the non-contact IC card 31 built in the mobile phone 25. The ID number of the registered member is read (step 27). The read ID number is transmitted from the POS terminal 27 to the computer 28 of the service provider 22 via the network 36 (step 28).

  The computer 28 collates the transmitted ID number with the ID number stored in the member information database 29. It is checked whether or not the ID number transmitted here is registered. The computer 28 transmits the collation result to the POS terminal 27 (step 29). The cashier determines the transmitted verification result from the display screen of the POS terminal 27 (step 30), and if the ID number of the user 24 is registered (OK), the cellular phone 25 of the user 24 is registered. A settlement process is performed in which the purchase price of the book 34 is subtracted from the amount charged to the book (step 31). At this time, in the settlement process, input of a personal identification number or presentation of an identification card may be requested in order to confirm membership.

  In the above example, the non-contact IC card 31 of the mobile phone 25 is provided with a settlement function and the book purchase price is settled by the mobile phone 25. Of course, cash settlement may be used.

  When the settlement processing is completed, completion information is transmitted to the computer 28 of the service provider 22 and transaction history information in the book information database 30 is updated. The transaction history information of the RFID tag 35 of the purchased book 34 and the non-contact IC card 31 of the mobile phone 25 is also updated (step 32).

  As shown in FIG. 7, the transaction history information of the book information database 30 and the RFID tag 35 includes the date 39a, the ID number 39b of the user 24, in addition to the ISBN code, classification code, serial number, and fixed price code of the book described above. The transaction content (sales or purchase) 39c and the store code 39d of the transaction book store 26 are comprised. With this information, it is possible to know who has purchased the book 34. As shown in FIG. 8, the transaction history information stored in the non-contact IC card 31 of the mobile phone 25 of the user 24 includes the date 40a, the ISBN code 40b of the book 34, the transaction content (purchase or sale) 40c, and the bookstore 26. Store code 40d.

  In the above description, an example is shown in which a new book 34 is purchased at a general bookstore 26, but the same processing is performed when, for example, a used book is purchased at a new old bookstore.

  Next, a method in which the user 24 sells a book at the new old bookstore (purchase from the new old bookstore) will be described with reference to FIG. FIG. 9 is a flowchart showing processing at the time of selling a book. First, the user 24 brings a book 34 to be sold to a purchase register at a new old book store (step 41). It is assumed that the POS terminal 27 and the non-contact IC card reader / writer 32 and the RFID tag reader / writer 33 connected to the POS terminal 27 shown in FIG. 1 are also provided in the new old bookstore, and the POS terminal 27 is connected to the computer 28.

  When the cashier takes the book 34 close to the RFID tag reader / writer 33, the information stored in the RFID tag 35 of the book 34 is read by the RFID tag reader / writer 33 (step 42), and the read data is transferred from the POS terminal 27 to the network 36. To the computer 28 of the recycling service provider 22 (step 43).

  The computer 28 of the recycling service provider 22 collates the transmitted data of the book 34 with the stored information in the book information database 30 and transmits the collation result to the POS terminal 27 of the new old book store (step 44). Here, it is checked whether or not there is data in the book information database 30 that matches the transmitted data of the book 34.

  The cashier determines the transmitted verification result from the screen of the POS terminal 27 (step 45). If the data match (OK), the cashier 25 requests the user 24 to present the mobile phone 25 (step). 46). If the data do not match (NG), it is determined that the data cannot be purchased and the process is terminated.

  When the user 24 presents the mobile phone 25, the cashier brings the mobile phone 25 close to the non-contact IC card reader / writer 32, and the non-contact IC card reader / writer 32 is recorded in the non-contact IC card 31 in the mobile phone 25. The member ID number is read (step 47), and the read ID number is transmitted from the POS terminal 27 to the computer 28 of the recycling service provider 22 via the network 36 (step 48).

  The computer 28 of the recycling service provider 22 collates the transmitted ID number with the information stored in the member information database 29 (step 49). Here, it is checked whether or not the user 24 who wants to sell the book 34 is a registered user (step 50). If the user is a registered user (OK), the transaction history information in the book information database 30 is checked next to determine whether or not to purchase (step 51).

  The purchase possibility determination method includes transaction history information recorded on the RFID tag 35 of the book 34, transaction history information recorded on the non-contact IC card 31 of the mobile phone 25, and transaction history recorded on the book information database 30. In the information, it is determined whether or not the contents of the latest transaction information (date and time, transaction contents and ID number of the user 24) match. If the user who purchased the book 34 is different from the user who is currently selling the book 34, the ID number recorded on the non-contact IC card 31 of the mobile phone 25 and the RFID of the book 34 are different. The ID numbers recorded in the tag 35 and the book information database 30 are different, and in this case, it is determined that the transaction contents do not match.

  If it is determined that the transaction contents do not match (NG in step 52), the computer 28 notifies the POS terminal 27 of the determination result of “impossible to purchase” and ends the processing. If it is determined that the transaction contents match (OK in step 52), the computer 28 notifies the POS terminal 27 of a determination result of “purchasable”. The POS terminal 27 that has received the notification of the “purchased” determination result displays the notification to the cashier on the screen. The cashier presents the purchase price determined in advance to the user 24 and performs a settlement process for charging the amount to the contactless IC card 31 of the mobile phone 25 of the user 24 (step 53). In this case, the user 24 may be paid in cash.

  When the settlement process is completed, completion information is transmitted from the POS terminal 27 to the computer 28 via the network 36, and the computer 28 updates the transaction history information in the book information database 30. The transaction history information of the RFID tag 35 in the book 34 and the transaction history information of the non-contact IC card 31 of the mobile phone 25 are also updated (step 54). The transaction history information of the book information database 30 and the RFID tag 35 is updated as shown in FIG. 10, and the transaction history information of the non-contact IC card 31 is updated as shown in FIG.

  That is, in FIG. 10, the transaction history information of the book information database 30 and the RFID tag 35 is updated with the date 39a, the ID number 39b of the user 24, the transaction content (sales or purchase) 39c, and the store code 39d of the transaction bookstore. . In this case, the previous transaction information is also recorded as a record. Further, as shown in FIG. 11, the transaction history information stored in the non-contact IC card 31 of the mobile phone 25 of the user 24 includes the date 40a, the ISBN code 40b of the book 34, the transaction content (purchase or sale) 40c, and the transaction. The store code 40d of the bookstore is updated. In this case as well, the previous transaction information is left, but when a certain amount of transaction information is accumulated, the old transaction information may be deleted.

  As described above, according to the above-described embodiment, the ID number of the user issued along with the member registration is stored in the non-contact IC card 31 built in the mobile phone 25, and the RFID tag 35 attached to the book and the information Transaction history information including purchaser information is stored in the book information database 30 as a recording device, and when the user 24 sells the book 34, the ID number in the non-contact IC card 31 and the RFID tag 35 or the book information database. By collating with the purchaser information in 30, it is possible to prevent the purchase of a book that has been properly purchased and then passed to a third party by unauthorized means.

  In the above-described embodiment, the contactless IC card 31 is built in the mobile phone 25 owned by the user, and the ID number and transaction history information are stored in the contactless IC card 31. You may make it use only with the non-contact IC card 31, without using. In this case, member registration is performed when the user goes to a bookstore or the like. Needless to say, the POS terminal 27 of the bookstore has a member registration function.

  In the above embodiment, when the user 24 sells the book 34, the transaction history information recorded on the contactless IC card 31 of the mobile phone 25 of the user 24 is recorded on the RFID tag 35 of the book 34. The transaction history information stored in the book information database 30 and the transaction history information recorded in the book information database 30 are collated, but the transaction history information of the non-contact IC card 31 is either the RFID tag 35 of the book 34 or the book information database 30. You may make it determine by making it collate with the transaction history information currently recorded on. When the transaction history information of the non-contact IC card 31 is collated with the transaction history information recorded on the RFID tag 35 of the book 34, the POS terminal 27 performs the collation.

  Next, another embodiment of the present invention will be described. This embodiment relates to a method for determining the selling price of second-hand goods and an assessment method at the time of purchase. As described in the above embodiment, in the present invention, transaction history information is stored in the database of the recycling service provider, the RFID tag of the product (book), and the contactless IC card of the user. By effectively using these transaction history information, it is possible to provide a fine-grained service to the user.

  As a first embodiment, a method for determining the purchase price of second-hand goods will be described. First, assume that the new selling price of book A is V yen, the used selling price is W yen, the purchase reference price is Z yen, and the magnitude relationship between each other is V yen> W yen> Z yen. Normally, when the book A is purchased, the purchase price is Z yen, but the book A can be obtained from the transaction history information stored in the database of the recycling service provider, the RFID tag of the product (book) or the contactless IC card of the user. Is purchased as a new book and is determined to be sold for the first time, for example, it can be purchased for Y yen higher than the standard purchase price Z yen (Y yen> Z yen). . As a result, when selling a book purchased as a new book, it becomes possible to sell it at a higher price than when selling a used article.

  As a second embodiment, when a used book A is purchased, the purchase price of the book A is usually W yen, but the database of the recycling service provider, the RFID tag of the product (book), or the non-contact of the user If it is determined from the ID number of the transaction history information stored in the IC card that the previously purchased person will purchase again, the selling price of the book A is X yen (W yen> X yen> Y) which is cheaper than W yen. Yen). As a result, when a person who has made a purchase previously purchases it again for rereading, it can be purchased at a low price.

  The role of analyzing the contents of the transaction history information is played by the computer 28 of the recycling service provider 22 or the POS terminal 27 of the bookstore. Further, the determination of new prices (the above Y yen and X yen) is performed by the POS terminal 27. By analyzing the contents of the transaction history information, it becomes possible to set a finer price according to the transaction status of the book, which can contribute to the improvement of services for users.

  In each of the above-described embodiments, a book has been described as an example of a recycled product. However, any product that can be attached with a readable / writable RFID tag can be applied to products such as clothes.

  Furthermore, it can be applied to a book lending system. In the case of a book lending system, the lending information is written to the RFID tag attached to the book at the time of lending and the contactless IC card of the person's mobile phone, and both the RFID tag and the contactless IC card are returned when the book is returned. By reading out the lending information recorded in, it is possible to lend and return business in a short time.
